Exosun, a provider of solar tracking technologies for utility-scale ground-mounted solar plants, now offers its Exotrack® HZ horizontal single-axis tracker with an intelligent patented backtracking process, called SMARTracking™.
Solar trackers orient PV panels toward the sun throughout the day, significantly increasing solar plant output in comparison to fixed-tilt structures. All solar tracker control programs include a standard backtracking system to minimize shading on PV modules during periods of low solar height. It usually relies on the theoretical positioning of the trackers on the plant, possibly followed by arduous on-site fine tuning.
When designing SMARTracking™, Exosun’s engineering teams took into account variations in the terrain and the real on-site implementation of the trackers, making SMARTracking distinguishable from its competitors. The genuine advance of SMARTracking™ is based on a three-dimensional positioning analysis of each solar tracker on site, thereby achieving the best alignment for the trackers and enabling to individualize the control of each solar tracker. Consequently, SMARTracking™ allows the plant to generate up to 5% more energy yield annually compared to other traditional single-axis trackers, maximizing ROI. For example, thanks to the implementation of SMARTracking™ on a 7 MW project in South West France, 440 MWh of electricity can be produced more per year.
Exosun’s Exotrack® HZ will be on display at Solar Power International, held October 21-23 in Las Vegas.
